Figure 1. In situ hybridization of staged sections
of rat seminiferous tubules. Stages of spermatogenesis in adult rats
are marked with white Roman numerals. A, B, C, D, and F, Darkfield; E,
brightfield. A–E, Antisense CYP51 probe; F, sense CYP51 probe.
White bar = 100 µm. G, Schematic pattern of CYP51 mRNA
expression during spermatogenesis in rat. Time, The projected length of
a particular stage in hours. The darker shading presents
more intense in situ hybridization signal.
